How can I undo the damage from a DIY furniture refinishing project?
I'm afraid you'll have to start over, which means stripping the finish down to the bare wood and sanding the surface smooth. There are many refinishing options depending on whether you want to repaint or stain and seal. For the best advice on product and technique, visit a paint store and talk to the owner. You won't be able to achieve a professional finish at home, but it should be possible to achieve an even color and glossy finish if that is your desire.
